Widmer is serving 15 years to life in prison for the 2008 murder of his wife Sarah, who drowned in the bathroom of their Hamilton Township home.

Attorneys began laying out their latest appeal Tuesday morning at the 12th District Court of Appeals.

Widmer's appeals team argued that the lead investigator on the case, Lt. Jeff Braley, lacked the proper qualifications to lead a homicide investigation and might have fabricated evidence and lied during his testimony.

"Braley has a reputation for dishonesty and is highly compelling evidence, your honor," Michelle Berry said.

Braley was forced to resign from his job with Hamilton Township police for fabrications on his resume following the third trial.

But prosecutors said that even if Braley lied, it would not have changed the trial's outcome.

"There is no evidence, anything as to Braley's alleged lack of credibility, that the integrity of the investigation was breached," assistant prosecutor Michael Greer said.

An attorney who has observed two of the three trials said he thinks this appeal could work out in Widmer's favor.

"The defense made a lot of good points. There is a pattern of lying, and things were not allowed to show or tell about to the jury, and that came across very well in the arguments," Mark Krumbein said.

The first conviction was thrown out by the presiding judge over jury misconduct, the second ended in a hung jury and the third ended with a conviction.

Ryan Widmer's father, Gary, said his son is holding up about as well as one could expect.

"I talk to him every day. He's doing as well as to be expected ... he obviously is not happy where he's at because he's not supposed to be there,but he's doing OK," he said.

The court has yet to rule on a previous appeal heard in April, and a decision won't likely be made on this appeal for 60 to 90 days.
